Abstract

Introduction. Successful economic and social development of urban territories requires a sustainable transport system that provides reliable connections between territories and a high level of their transport accessibility for the daily social and economic activities of the population. The most important elements of the transport and planning framework of the agglomeration are linear objects, represented by transport corridors, which determine the bulk of transport costs for population movements, and hence transport accessibility of territories. A high level of transport service in such important elements as transport corridors directly affects the formation of sustainable daily migrations of the population and the development potential of the adjacent territories, and therefore affects the formation of the agglomeration boundaries. Materials and methods. For the territory of Irkutsk agglomeration, which includes Irkutsk city as the main core of agglomeration, satellite cities Angarsk and Shelekhov and the surrounding territory of Irkutsk district, approaches to the formation of a unified transport model of agglomeration as the main tool for assessing transport demand, analyzing the distribution of traffic flows and indicators of the effectiveness of measures to develop the territories of transport corridors and the territories served by them are proposed. The paper considers special cases of the constituent parts of the models for assessing transport demand for movements between individual municipalities. An approach to estimating transport demand on adjacent conjugate transport corridors, previously used only for individual corridors is proposed. Results. The significance indicators of transport corridors, including the volume of transport work in relation to their total length were obtained. The example of the application of transport model of Irkutsk agglomeration to solve the problems of the formation of new transport corridors is presented. Conclusions. It is concluded that the proposed approaches to the formation of the transport model allow to prepare the necessary tools in conditions of limited opportunities for mass surveys, as well as maximize the use of existing transport models developed earlier for individual municipalities and transport corridors, combining them into a single transport model.

城市运输走廊在结块形成中的作用
介绍。城市地区成功的经济和社会发展需要一个可持续的运输系统,在各领土之间提供可靠的联系,并为人口的日常社会和经济活动提供高水平的运输可达性。城市群运输和规划框架的最重要要素是线性对象,以运输走廊为代表,它决定了人口流动的大部分运输成本,从而决定了领土的运输可达性。交通走廊等重要要素的高水平运输服务,直接影响到人口每日可持续迁移的形成和邻近领土的发展潜力,从而影响到集聚边界的形成。材料和方法。对于伊尔库茨克城市群,包括伊尔库茨克市作为城市群的主要核心,卫星城市安加尔斯克和舍列霍夫以及伊尔库茨克地区的周边地区,接近形成一个统一的城市群运输模型,作为评估运输需求的主要工具;分析了交通流量的分布,并提出了发展交通走廊及其所服务的区域的措施的有效性指标。本文考虑了评估各个城市之间的交通需求的模型的组成部分的特殊情况。提出了一种估算相邻共轭运输通道运输需求的方法,这种方法以前只用于单个运输通道。结果。获得了交通走廊的显著性指标,包括交通量与总长度的关系。最后以伊尔库茨克城市群交通模型解决新交通走廊形成问题为例。结论。结论是,拟议的形成运输模式的方法可以在进行大规模调查的机会有限的情况下准备必要的工具,并最大限度地利用早先为个别城市和运输走廊开发的现有运输模式,将它们合并成一个单一的运输模式。
